# HISTORY:
#
# Apache configuration script, first cut --- rst.
# Don't like it?  Inspired to do something better?  Go for it.
#
# second cut --- jmj
# At this point we change what Configuration contains. It maintain
# contains comments, specific compiler flags, a list of included
# modules and "rules". These rules are used to allow Configure to
# be totally configured from Configuration.
#
# third cut --- rse
# Big cleanup of the generated Makefiles and remove of
# some old kludges

# Uses 6 supplemental scripts located in ./helpers:
#	CutRule: Determines the value for a specified Rule
#	GuessOS: Uses uname to determine OS/platform
#	PrintPath: generic "type" or "whence" replacement
#	TestCompile: Can check for libs and if $(CC) is ANSI
#	 (i.e., a simple "sanity check")
#	mfhead:
#	fp2rp:
#	slo.sh:

## Find out what modules we want and try and configure things for them
## Module lines can look like this:
##
##  Module  name_module    some/path/mod_name[.[oa]]
##  AddModule              some/path/mod_name[.[oa]]
##
## In both cases, the some/path can either be an arbitrary path (including
## an absolute path), or a path like "modules/DIR", in which case we _might_
## auto-generate a Makefile in modules/DIR (see later).
##
## The first case is the original style, where we give the module's
## name as well as it's binary file location - either a .o or .a.
##
## The second format is new, and means we do not repeat the module
## name, which is already part of the module source or definition.
## The way we find the module name (and other optional information about
## the module) is like this:
##
##  1 If extension is not given or is .c, assume .o was given and goto 3
##  2 If extension if .module, go to D1
##  3 If extension is .o, look for a corresponding .c file and if
##      found, go to C1
##  4 If no .c file was found, look for a .module file (Apache module
##      definition file). If found, go to D1
##  5 Assume module name is the "name" part of "mod_name", as in
##      name_module.
##
## If a C file is found:
##
## C1 Look for module name given by an MODULE: line (e.g. MODULE: name_module)
##      If found assume module contains a definition, and go to D1
## C2 If not found, look for a module name given on the declaration of the
##      module structure (e.g. module name_module).
## C3 If neither given, go to 4 above.
##
## If a definition file is found, or a .c file includes a module definition:
##
## D1 Get the module name from the MODULE: name= line
## D2 Get other module options (libraries etc). To be done later.
##
##
## For now, we will convert the AddModule lines into Module format
## lines, so the rest of Configure can do its stuff without too much
## additional hackery. It would be nice to reduce the number of times
## we have to awk the $tmpfile, though.

## MODFILES contains a list of module filenames (could be .c, .o, .so, .a
##    or .module files) from AddModule lines only
## MODDIRS contains a list of subdirectories under 'modules' which
##    contain modules we want to build from both AddModule and Module
##    lines
